Coughlin broke up a viable partnership. I can believe he/she/they were no longer happy, regardless of their public face. The article definitely reads as a public relations ploy, but I don't think it's unfair.
No, I don't think it's unfair either.. what can we expect them to say after all , we couldn't stand each other ,so I dumped him/her when I saw there was another prospective partner available ?...or I'd been secretly keeping my eye open for about 6 mo's ?..or whatever... we wouldn't want them to stay together being miserable ,surely.
I hope Caitlin can find a partner that looks a better match for her.
